Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

Download or read book Assessing Cumulative Human Impacts on Northern Woodland Caribou with Traditional Ecological Knowledge and Resource Selection Functions written by Jean Lieppert Polfus and published by . This book was released on 2010 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woodland caribou (Rangifer tarandus caribou) are federally listed and declining across Canada because of the cumulative impacts of human infrastructure development. The Atlin northern mountain herd, in the territory of the Taku River Tlingit First Nation (TRTFN), British Columbia, is less affected by development than southern herds. However, recent low productivity in this herd suggests that the impacts of development (i.e., roads, mines, cabins and towns) may be accumulating. To predict the cumulative impact of human development on the Atlin herd, we developed seasonal resource selection functions (RSF) at 2 spatial scales with data from 10 global positioning system collared caribou. We modeled habitat selection and assessed cumulative effects by estimating the zone of influence (ZOI) around several types of human development. At the landscape and home range scale caribou avoided the ZOI and selected pine-lichen forests in winter and alpine habitats in summer. Approximately 8 and 2% of high quality habitat was lost due to avoidance of current development at the landscape scale in winter and summer, respectively. Future development of access roads to 2 mines would cause a further loss of 1% of high quality habitat. Negotiating the complex political dynamics that surround caribou conservation often requires new approaches to management and recovery planning. The incorporation of traditional ecological knowledge (TEK) with Western science could improve efficiency of management decisions and enhance the validity and robustness of ecological inferences. Therefore, we evaluated how well RSF and TEK habitat models predicted current woodland caribou observations and compared the spatial predictions of both modeling approaches. Habitat suitability index models were generated from TEK interviews with TRTFN members. Though comparison of habitat ranks between the 2 models showed spatial discrepancies in some cases, overall, both approaches had high model performance and successfully predicted caribou occurrence. Our results suggest TEK can be used to identify caribou habitat and is a useful approach in northern ecosystems that frequently lack long-term ecological data that are needed to inform management decisions. Combining TEK-based habitat suitability index models with cumulative effects assessments will facilitate recovery goals for woodland caribou across northern Canada.

Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the Grand Rapids Dam in the 1960s, hydroelectric development has dramatically altered the social, political, and physical landscape of northern Manitoba. The Nelson River has been cut up into segments and fractured by a string of dams, for which the Churchill River had to be diverted and new inflow points from Lake Winnipeg created to manage their capacity. Historic mighty rapids have shrivelled into dry river beds. Manitoba Hydro's Keeyask dam and generating station will expand the existing network of 15 dams and 13,800 km of transmission lines. In Our Backyard tells the story of the Keeyask dam and accompanying development on the Nelson River from the perspective of Indigenous peoples, academics, scientists, and regulators. It builds on the rich environmental and economic evaluations documented in the Clean Environment Commission’s public hearings on Keeyask in 2012. It amplifies Indigenous voices that environmental assessment and regulatory processes have often failed to incorporate and provides a basis for ongoing decision-making and scholarship relating to Keeyask and resource development more generally. It considers cumulative, regional, and strategic impact assessments; Indigenous worldviews and laws within the regulatory and decision-making process; the economics of development; models for monitoring and management; consideration of affected species; and cultural and social impacts. With a provincial and federal regulatory regime that is struggling with important questions around the balance between development and sustainability, and in light of the inherent rights of Indigenous people to land, livelihoods, and self-determination, In Our Backyard offers critical reflections that highlight the need for purposeful dialogue, principled decision making, and a better legacy of northern development in the future.
Download or read book Home Range and Core Area Determination Habitat Use and Sensory Effects of All Weather Access on Boreal Woodland Caribou Rangifer Tarandus Caribou in Eastern Manitoba written by Doug W. Schindler and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada's boreal woodland caribou (Rangifer tarandus caribou Gmelin) are listed as "Threatened" under the Canadian Species at Risk Act (SARA) and provincially under the Manitoba Endangered Species Act (MESA). Two of three provincially designated high-risk boreal woodland caribou ranges occur in eastern Manitoba and have been studied using Global Positioning System (GPS) tracking technology. This project was undertaken with the cooperation of the Eastern Manitoba Woodland Caribou Advisory Committee (EMWCAC). I investigated the development of an objective criterion using an adaptive kernel analysis to define core areas of use and the sensory effects of all weather access. A Habitat Suitability Index (HSI) model for woodland caribou was evaluated to determine if woodland caribou were selecting high quality habitat as defined by the model. Habitat use and selection at course and fine scales was assessed to determine landscape and stand level selection and use. A case study of habitat use and selection using forest inventory attribute data was also conducted and a comparative analysis was undertaken to determine differences in habitat use and selection between two ecologically distinct caribou populations. The criteria used to define core areas yielded mapping outputs that could provide a surrogate for critical habitat and a basis for management zoning and habitat planning. Analysis of the animal use of high quality habitat as predicted by the HSI model illustrated that woodland caribou selection of high quality habitat versus its availability is significant. Course or landscape scale habitat selection and use analysis illustrated that woodland caribou require large tracts of jack pine dominated forest containing black spruce, treed rock and muskegs. At the fine or stand level scale, woodland caribou selected habitat based on discrete variables described in the forest inventory attribute data. Woodland caribou preferred 60 - 80 year old pine dominated forest with a crown closure greater than 50%, interspersed with black spruce, rock outcrop and treed muskegs. Woodland caribou habitat containing greater proportions of treed rock and muskeg in pine dominated forest was important to woodland caribou in eastern Manitoba. The effects of the Happy Lake Road on woodland caribou use and animal energetics are measurable. Woodland caribou illustrate avoidance at approximately 2 kilometres from the road with maximum use of habitat occurring at 9 kilometres from the road. The location of the Happy Lake Road may be favourable considering the location of the Black River. Avoidance of the Happy Lake Road by the Owl Lake animals may be a function of predator and human avoidance. General management implications from this study include the use of the objective criteria for adaptive kernel analysis to determine ecologically representative core use areas that can be used in integrated management zoning. It also has application as a tool for proactive monitoring in the determination of core areas and critical habitat in resource development and mitigation.

Book excerpt: Forest fire is the primary natural disturbance process influencing the distribution and abundance of terrestrial lichens across ranges of woodland caribou (Rangifer tarandus caribou), including the Klaza Caribou Herd in west-central Yukon. I used stand and understory data to understand variation in the abundance of lichens in burns of various ages. Focusing on the distribution of individual caribou, I used a dataset of GPS collar locations to examine resource selection on the winter range and within burns. Results suggested that burns provided suboptimal habitat for the KCH until 50 years post-fire; however, analyses focused on the use of burned habitat indicated that they regularly encountered burns and opportunistically used remnant lichen within the burn perimeter. The relationship between caribou and burned landscapes is complex and non-linear indicating that wildlife managers should look beyond burn age to account for the effects of fire on the availability and quality of caribou habitat.

Book excerpt: This study analyzes the number of forest fires in Saskatchewan, the area burned, the fire cycle, the fire season, causes of fires, potential fire intensity, and the fire climate for two types of ecological units: ecozones & ecoregions. Analyses are performed for all forested ecozones: the boreal plain, the boreal shield, & the taiga shield. For ecoregions, only those of the boreal plain were considered. The analysis is based on 20 years (1981-2000) of fire occurrence (ignition) data, a database of large (over 200 hectare) fires for 1945-2000, and 12 years (1990-2001) of daily fire weather observations. The results reveal contrasts in the fire regime of ecozones & ecoregions and illustrate important variations in the fire regime in both time & space.
